Since I have been growing my hair long, I have tried an array of brushes.  The latest is the John Freida Porcupine Brush

• Deep-shine silicone strips create shine, smooth flyaway hair and help reduce frizz.
• Silicone lasts for the life of the product.
• Tourmaline – 100% crushed gemstones release natural IONS for intense shine.
• IONS help flatten hair’s cuticle layer, leaving hair looking shiny and reducing frizz.
• Use with the John Frieda^® Full Volume Dryer to increase benefits.
• Combination of nylon and boar bristles distributes the scalp’s own natural oils for added shine and smoothness.
• Use to straighten curly or wavy hair or add volume and curl.
